Provide complete steps to solve the above question any help is appreciated
How much heat would be given off per mole of NaOH if 4.6g of NaOH dissolves to give off 755J of heat? b)How many grams of NaOH are needed to produce 88 kJ of heat
A radioisotope of iodine 131I is utilized to study thyroid function. A patient is given a sample that is 1.7 * 10-4 M 131I. If the half life is 8.04 days define what fraction of the radioactivity remains after 32.0 days. Radioactive decay is a fir..
a student mixed 5.00 ml of a nickel2 chloride solution with 5.00 ml of .100m sodium phosphate and a precipitate formed.

What is the activation energy in kJ of a reaction whose rate constant increases by a factor of 10 upon increasing the temperature from 303 K to 333 K
A blast furnace is the main unit in the production of iron from iron ore. One can view the blast furnace as a process in which the principal desired reaction is:
When 50.0 mL of water containing 0.50 mol HCl at 22.5°C is mixed with 50.0mL of water containing 0.50 mol NaOH at 22.5°C in a calorimeter, the temperature of the solution increases.
If there is no such evidence, then we have no reason to believe in witches. If there is evidence, we do have reason to believe in witches. There is no such evidence. Therefore we have no reasons to believe in witches.
The system then re-equilibrates. The appropriate chemical equation is PCl3(g)+Cl2(g) PCl5(g) Calculate the new partial pressures of PCl3, Cl2, and PCl5 after equilibrium is reestablished.
